Within the last couple of years I had to move my two horse-sized geldings and a pony gelding from a close-knit barn. It was so hard to find a spot for them at a new good barn that I ended up having to long term free lease the pony to a family friend. I can’t even imagine having to move 5+ horses.
My problems were nowhere near as bad as the OP’s. That said, I 100% understand people not saying anything about a higher-profile trainer, or a trainer in a close knit ‘barn family’. My moving was apparently the straw that broke the camel’s back. Within a month, another girl on the show team left, and within a year all of the ‘original’ show team members left and only one is left (she lessons and leases, doesn’t own). My friend (the first to leave after me) tried to have a nice conversation with trainer about giving her notice and was being practical (the new barn is 5 minutes from her house vs 35, thank you for all that you’ve done for me/my horse, etc). Friend was told that her horse was too much for her (trainer picked him out of course) and “you’ll be back in two months.” Friend left in tears. I have heard from several different horse professionals that my former trainer still badmouths all of us (teenagers, and some of us are lower 20s/in college) to anyone that will listen, and that we won’t get anywhere with our horses.
Family doesn’t make you feel like **** for moving for the sake of your horse. I don’t associate with former trainer/BO whatsoever, while I am still in regular, positive contact with the BO before her.
Hang in there OP. I am so, so very sorry for your losses. I hope you have some good horsey luck soon and that you and your critters have a soft spot to land soon.
